DENNIS X. COAKLEY, OF HAVERHILL, MASSACHUSETTS, ASSIGNOR 0F ONE-HALF TO JOE W. BEAN, OF HAVERHILL, MASSACHUSETTS.

DRINKING-FOUNTAIN.

To all whom it may concern:

Be it known that I, DENNIS X. CoAKLnY, residing at Haverhill, in the county of Essex and State of Massachusetts, have invented an Improvement in Drinking-Fountains, of which the following is a specification.

This invention relates to certain improvements in that class of drinking-fountains known as bubblers, in which a jet of water is directed vertically, so that a person may drink from the crest of the stream, the nozzle being frequently, although not necessarily, arranged in a basin which catches the water as it flows from the nozzle and holds it at a level which is slightly above the upper end of the nozzle, so that the force of the jet is, to a degree, arrested, and the crest of the stream made more uniform. When these devices are used in schools, the children are likely to play with the flowing water by placing a finger on the end of the nozzle, so that a forcible stream will be thrown horizontally from the device. This difliculty has been obviated to an extent by providing outlet ports in the supply-pipe, adjacent the jet, but, with this arrangement, when the device is used in places where it is desired that the water run constantly, it occasions a large loss of water.

The principal object of my invention is to provide a device of the above described character which is so constructed that it will be impossible for the water to be thrown horizontally by obstructing the nozzle which throws up the stream and which will be so arranged that there will be no unnecessary waste of water.

A further object of my invention is to provide a device of the above described character which shall be simple in construction and sufliciently durable to withstand the usage to which it is likely to be subjected.

I accomplish this object by the means shown in the accompanying drawing, in which,

Figures 1 and 2 are central longitudinal sectional views on the line 11 of Fig. 3. Fig. 3 is a plan view of the device, Fig. 4 is a detail sectional view of the discharge nozzle.

According to my invention I provide a standpipe, or vertically disposed chamber a Specification of Letters Patent.

having a threaded nipple b at its lower end, to which the water supply-pipe may be con nected, and having a cap 0 for closing its upper end. The lower end of the standpipe a is closed by a partition (Z, in which a supply-pipe is mounted, said pipe extending through said partition (Z and opening at its lower end into said nipple Z). Said pipe 6 is extended upwardly within the standpipe a, and is bent at right angles so that it extends horizontally to the wall thereof, at which point it is reduced to provide an ejector nozzle 6. A bracket f, in the form of a pipe, is mounted at one end in the wall of the standpipe a, adjacent its lower end and extends horizontally therefrom for a suitable distance, and a casing g is mounted on the end thereof, said pipe f preferably ex tending through the adjacent wall of said casing, abutting on the inner side of the opposite wall, and being securely soldered at both points, so that the casing is rigidly supported by said pipe. The lower portion of said pipe f at its end, is cut away to provide an open passage f between the interior thereof and the interior of the casing g. The lower end of the casing g is provided with an opening and the.walls of the casing about said opening are preferably provided with slots 9 for a purpose to be explained.

A basin 71. is provided in the upper portion of the casing g which is united to the latter at its rim, and this rim is made rounding so that overflowing water will run down the side of said casing. A jet pipe 1' is arranged within and extends centrally of the pipe 1, and the intake end of pipe 2' passes through the wall of the standpipe a, and has a flared end a" which opens therein in alinement with the nozzle 6, the latter extending for a short distance into the flared end of the pipe 2' butout of contact therewith to provide a tapering annular space therebetween, the sides of the nozzle 6 and the inner wall of the flaring end i being approximately parallel and relatively constructed and arranged in the form of an ordinary water ejector, as shown in Fig. 4. This annular space should have an area as great as the area of the nozzle e, for reasons which will appear. The pipe 2' extends to the middle of casing g and then extends vertically through the bottom of the basin h at its middle and terminates in a nozzle 2' at a suitable distance there above, preferably a small fraction of an inch below the level of the rim of the basin.

An overflow pipe j is connected to the standpipe (4 adjacent its upper end, said pipe j extending obliquely downward and being connected to and opening into the supporting pipe 7, adjacent the casing g.

V'Vith the above described arrangement the operation is as follows:-A properly regulated supply of water is delivered to the nipple b and thence discharged through the nozzle 0 into pipe 2', the force of the dis charge carrying the water through the pipe 5, so that a jet is discharged through its nozzle 2' The basin 7i will immediately fill, so that the end of nozzle 2' will. be slightly submerged and the jet will be discharged through the water in the usual manner, as indicated in 1* 1.. If the water pressure is low, and, as the flow of the water is somewhat obstructed, some of the water discharged from the nozzle 6 will pass back through the annular space between said nozzle and the entrance to the pipe 2', and the water will back up in the standpipe a and partly fill the same. The overflow pipe j is connected to the standpipe at a point somewhat above the crest of the stream which is delivered from the nozzle 2', so that when the water level has been raised approximately to the level indicated in Fig. 1 in the standpipe, which is some distance below the point of connection of the overflow pipe j, thereto, it will not be raised any farther, as the head of water will then be sui'licient to prevent back How past the nozzle e. In case, however, the water pressure is high, then the nozzle 6 and flaring end i will act as an ejector and will prevent accumulation of the water in the standpipe, air being drawn therefrom by the ejector and supplied thereto through the pipe 7'. Under all conditions of pressure suliicient to cause a jet to be discharged, the ejector action will be sutlicient to decrease, to some extent, the height to which the water will rise in the standpipe, but, under none of these conditions will the water level be raised to an extent sui'iicient to cause the water to overflow into the pipe 7'. If, however, the nozzle 2" should be obstructed, as indicated in Fig. 2, then the water will flow back past nozzle 0 into the standpipe a and overflow into the pipe y and be discharged through pipe f and opening f and through the opening The slots about the opening 5/ are pro vided to make it ditlicult, or practically impossible to defeat the object of the invention by obstructing the opening 9 and then pressing the finger on the nozzle 6, said slots permitting the discharge of water in case the opening 9' is obstructed. Obviously openings in the walls of the casing g at any other points would accomplish the same result.

It may be observed that the pipe j, as arranged, acts as an effective brace for the pipe 7 in supporting the casing g.
